The first all-India census was conducted in 1872 during British India. However, the first regular and comprehensive census was held in 1881, and since then, it has been conducted every ten years. The most recent census was carried out in 2011, with the next one scheduled for 2021, though it was delayed due to the Covid-19 pandemic.
The census is managed by the Registrar General and Census Commissioner of India, who operates under the Ministry of Home Affairs. The primary purpose of the census is to collect detailed demographic, social, and economic data across the country. This data is crucial for formulating policies, allocating resources, and planning developmental activities at both the central and state levels. It serves as an essential tool for governments to make informed decisions on a wide range of issues, from infrastructure development to healthcare and education, helping ensure that resources are distributed equitably and effectively across the nation.
